- Pressure · air
- 2–2.2 barrecommended
- Spray viscosity
- 18–24 s DIN4 / VZ-4 @20 °Crecommended
- Consumption
- 150 g/m² per coatofficial
- Wet film
- 150–165 µmrecommended
- Coats
- 2 coatsrecommended
- Flash-off

- Recoat · Wet-on-dry (h)

- Sanding between coats
- P320–P400 denib, dust off, no heavy sanding through to primerrecommended
150 g/m² per coat is the official figure. Nozzle/pressure are an engineering recommendation — Technocolor doesn't publish them. Fan fully open, 15–20 cm distance, 50–75 % overlap.
Conventional spray

- 1.4–1.6 (typ. 1.5) mmrecommended
- Pressure · air
- 3–3.5 barrecommended
- Spray viscosity
- 18–22 s DIN4recommended
- Consumption

Air spray is the only method Technocolor lists (catalog, website).
Airmix (air-assisted airless)

- 0.23–0.28 mmrecommended
- Pressure · fluid
- 40–80 barrecommended
- Pressure · air
- 1–2 barofficial
- Spray viscosity
- 20–26 s DIN4recommended
Airmix is better suited to topcoats than airless (Technocolor methods page). For production runs.
Airless
- Nozzle
- 0.23–0.28 mmrecommended
- Pressure · fluid
- 100–150 barrecommended
Not recommended for the topcoat: Technocolor positions airless mainly for primers on large flat parts; finish quality at 30/60 gloss suffers.
Process and compatibility
- Substrate preparation
- Wood at 12–15 % MC for exterior joinery, sand P150–P180, dust off. Seal end grain and joints thoroughly. Then ATS60003 (150 g/m²), sand P280–P320.recommended
- Goes over
- ATS60003
- Sanding
- Intercoat P320–P400 denib only. Do not sand or polish the final 30/60-gloss coat.recommended
- Temperature and humidity
- Material and room 18–25 °C, RH 50–70 %; don't spray in direct sun, on wet or cold (<15 °C) wood.recommended
- Don'ts
- Don't use over other primers — the system is ATS60003 only (catalog)
- Don't exceed the 4 h pot life at 20 °C
- Don't brush — Technocolor lists spray only
- Don't leave AC40 open — the hardener reacts with air moisture
Storage
- Packaging
- 1 л,5 л,25 лdealer
Safety: Flammable, solvent-borne; AC40 hardener contains isocyanates. Spray in a ventilated booth, wear an A2P2 organic-vapour respirator (or air-fed), nitrile gloves and eye protection.
